Absolutely the worst buying experience of my life

If I could give a rating of -5 stars, I would. I agreed to trade in my vehicle with Mad Cars, pending inspection. I drove 150km for the inspection and test drive, and everything checked out—except for a cracked windscreen, which I was asked to fix. I did so promptly. They then delivered the new vehicle to my home and drove away my old one. That’s when the problems began. The following evening, I received a call from the manager claiming my old vehicle had broken down upon arrival and had multiple issues. I explained that the car had been recently serviced with no reported problems, and there were no warning signs when they collected it. Despite this, I was told I had two options: either cancel the entire deal and return their vehicle, or keep the new one and take back my old car to fix it myself. I expressed that this was unfair—the vehicle broke down in their possession, not mine. After a week of silence and multiple follow-ups, I reluctantly agreed to take back my old car just to resolve the matter, as I couldn’t afford to fight it legally or pay two monthly installments. It took three weeks—and many pleas—to get my old vehicle returned. Meanwhile, the bank deducted the installment for the new car. To make matters worse, the new vehicle had worn shocks, bald tires, and a faulty center bearing—all of which I reported within a week of delivery. My emails and messages have been ignored, and it seems I’ll have to fix these issues myself to avoid further damage. If Mad Cars is reading this, the issue is far from resolved. You have my contact details at your Randburg branch. I’m still open to resolving this amicably.
